Affected versions
- unbound < 1.25.2
By system
1 still vulnerable, 1 fixed. Where VuXML applies (FreeBSD, DragonFly, FreeBSD's derivatives) a port is vulnerable while its version is in a range; pkgsrc says itself whether it lists a CVE of this advisory; OpenBSD and MidnightBSD keep no list this site reads, so their row is only an estimate: FreeBSD's ranges applied to upstream's version.
| System | Port | Version | State | Fixed |
|---|---|---|---|---|
| FreeBSD | dns/unbound | 1.26.2 | fixed | |
| MidnightBSD | dns/unbound | 1.26.1 | out of range, by version | |
| DragonFly | dns/unbound | 1.22.0_1 | vulnerable since 2026-07-25 |
